A method, performed by an image processing device, of encrypting image data includes: selecting an encryption target unit from among a plurality units constituting an image; generating a table including identification information about the encryption target unit; generating a first encryption unit including data obtained by encrypting the encryption target unit; generating a second encryption unit including data obtained by encrypting the table; and generating a bitstream including the first encryption unit, the second encryption unit, and units other than the encryption target unit among the plurality of units constituting the image.

A client computing system inserts selected advertising into digital content. Ads may be inserted into content based on a dynamic advertising matching process that is securely implemented within a hardware-based root of trust. User profiles used in ad matching may be privacy protected and maintained with confidentiality protection in the client computing system and/or a service provider server, respectively. When a client computing system makes a request to the service provider server for content with specified ad slots, the request may be made with the client's EPID signature, which is inherently privacy protected. The hardware-based root of trust protects insertion of selected ads into the linear rendering flow of the content.

There is provided an information processing apparatus and method capable of more easily comparing 3D objects. Comparison information which is information for displaying a plurality of 3D objects of 6DoF content in a comparable manner is generated. Further, the plurality of 3D objects of the 6DoF content is displayed in a comparable manner on the basis of comparison information which is information for displaying the plurality of 3D objects in a comparable manner. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, an information processing system, and the like.

A method for dynamic content filtering includes accessing, by a processing unit, a media content that includes several content portions. The method further includes determining a rating tag associated with each content portion from the media content, and a user profile of a user requesting the media content to be rendered. The user profile contains a permission level for the user. The method further includes filtering the content portions from the media content based on the permission level, wherein, in response to the rating tag of a particular content portion exceeding the permission level in the user profile, filtering out the particular content portion. The method further includes rendering content portions that were not filtered out.

Provided are methods and systems for controlling data such as content and/or application data transmitted to one or more user devices. One method can comprise receiving a request for first content and generating, in response to the request for the first content, a first transport stream comprising the first content and application data relating to a first application. At least a portion of the first transport stream is transmitted to a recipient device. An interruption in the transmission of the first transport stream is detected and a determination is made that only a first portion of the application data has been transmitted to the recipient device. A second transport stream including second content and a second portion of the application data is generated and transmitted.

Disclosed are a broadcast signal transmitter, a broadcast signal receiver, and a method for transceiving a broadcast signal in the broadcast signal transmitter/receiver. A method for transmitting a broadcast signal comprises the following steps: signaling in-band signaling information to at least one of a service component physical layer pipe (PLP) including at least one service component of a broadcast service, a first information PLP including first service information applied to one broadcast service and a second information PLP including second service information applied commonly to a variety of broadcast services; performing the FEC encoding on data included in each PLP; performing time-interleaving on the FEC encoded data; generating a transmission frame including the time-interleaved data; and modulating the transmission frame and transmitting a broadcast signal including the modulated transmission frame.

The present application discloses an intelligent processing method and system for video data, wherein, in the method an intelligent camera set a warning rule, the method comprises: the intelligent camera collecting video data and analyzing the collected video data in real time, generating intelligent data if the warning rule is met, which intelligent data contain an encoder identifier and motion trajectory information; the intelligent camera packaging the video data and the intelligent data into a program stream and sending it to a frame analyzing component in a cloud storage system; the frame analyzing component unpacking the received program stream to obtain the video data and the intelligent data, and storing the video data and the intelligent data in storage components respectively; the storage components sending storage address information of the video data and the intelligent data to an index server for recording respectively. The solutions of the present application can perform intelligent processing for the collected video data in real time.

Simplifying subtitle display processing in a variable speed reproduction mode on the receiving side is intended.

A video stream formed with a video packet having coded image data in a payload is generated. A subtitle stream formed with a subtitle packet having subtitle information in a payload is generated. A multiplexed stream including the video stream and the subtitle stream is generated and transmitted. In generating the multiplexed stream, the subtitle packet is arranged at a random access position.

The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

A method for transmitting broadcast signals by an apparatus for transmitting broadcast signals, the method includes encoding service data according to a 16200 bit codeword and a 11/15 code rate based on addresses in a parity check matrix, wherein the encoded service data comprises information bits and parity bits; building at least one signal frame by mapping the encoded service data; modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) scheme; and transmitting broadcast signals having the modulated data, wherein the encoding of the service data comprises: initializing the parity bits, adding the information bits to the parity bits of which addresses are based on values of entries in each row of the parity check matrix, wherein a row of the parity check matrix corresponds to a 360 bit group of the information bits.
